qconfirm
qconfirm-check - request delivery confirmation under qmail
in
.qmail:
|qconfirm-check [-mnbD] [-d dir] [-i bytes] [-t timeout] [prog]
qconfirm-check
(perhaps) requests delivery confirmations from the envelope sender to allow
further processing in the .qmail file.
qconfirm-check can operate either sender-based
or message-based, see below for sender mode and message mode.
Messages with
an empty envelope sender and the envelope sender <#@[]> are allowed by default.
WARNING: If you create a .qmail file to enable qconfirm-check, make sure
to also add a line specifying delivery to your normal mailbox.
If
qconfirm-check runs in sender mode, messages from known envelope senders
are accepted without a confirmation, and immediately allowed to be processed
further in the .qmail file.
qconfirm-check defers messages from unknown envelope
senders temporarily, and sends a confirmation request message to the sender.
The original message and all newer messages from the same sender will be
deferred temporarily until a reply to the confirmation request is received.
A message bounces if queuelifetime has expired. New messages from the same
sender do not result in new confirmation requests.
Once an envelope sender
has confirmed a delivery, qconfirm-check treats this envelope sender as
known.
If qconfirm-check runs in message mode (option -m is set),
each single message needs to be confirmed to be allowed to be processed
further in the .qmail file.
A message bounces if queuelifetime has expired.
- -m
- message mode. qconfirm-check identifies the message by its inode.
Each message must be confirmed before it is allowed to be processed further
in the .qmail file. Without this option qconfirm-check runs in sender mode.
- -n
- no acknowledge. Do not acknowledge the receipt of a reply to a confirmation
request.
- -b
- bad. Only works in sender mode. After checking if the envelope
sender is currently pending or ok, check if it is matched as bad.
- -D
- no domain
match. Only takes effect in sender mode. Don’t use extended envelope sender
address matching for domains and sub-domains. This applies for matching senders
for ok and bad.
- -d dir
- Override the default qconfirm directory (‘‘~/.qconfirm’’)
and the environment variable QCONFIRM_DIR with dir.
- -i bytes
- include the
top bytes bytes of the sender’s message at the bottom of a confirmation
request or acknowledgement. Default is 8192.
- -t timeout
- Set the timeout for
sending confirmation requests as reminders to timeout seconds. Unaccepted
and unconfirmed messages are held in the queue. Whenever qmail tries to
deliver the message, qconfirm-check checks if timeout or more seconds have
expired since a confirmation request was sent. If so, qconfirm-check again
sends a confirmation request as reminder. If timeout is zero, only one confirmation
request per message or sender is sent and no reminders. Default is 345586
(ca. four days).
- prog
- prog can be omitted or consists of one or more arguments.
If prog is set, qconfirm-check sets the environment variable QCONFIRM_DIR=dir
and runs prog just before requesting a delivery confirmation. If prog exits
zero, qconfirm-check allows the message to be processed further in the .qmail
file without a confirmation and exits immediately. If prog exits 111, qconfirm-check
exits 111 immediately. In all other cases qconfirm-check continues and requests
a delivery confirmation.
qconfirm-check reads its configuration
from files in the subdirectory conf/ of the qconfirm directory (normally
‘‘~/.qconfirm/conf/’’). Only the first line of a configuration file is considered.
- QCONFIRM_MAILNAME
- The configuration file QCONFIRM_MAILNAME overrides the
default mailname in the from header of confirmation requests and acknowledgements
(‘‘qconfirm’’).
- QCONFIRM_EXT
- The configuration file QCONFIRM_EXT overrides the
default extension used for receiving message confirmations (‘‘qconfirm-’’).
- QCONFIRM_PREPEND
- This configuration file must be set if the mail address you run qconfirm
for is controlled through qmail’s virtualdomains. It must be set to the prepend
part of the corresponding entry in /var/qmail/control/virtualdomains plus
a dash at the end.
- QCONFIRM_HOST
- The configuration file QCONFIRM_HOST if
set overrides the environment variable HOST normally set by qmail-local(8).
- QCONFIRM_ACCEPT
- The configuration file QCONFIRM_ACCEPT overrides the default
invocation of qconfirm-accept(1) in automatically created .qmail files (‘‘qconfirm-accept’’).
- QCONFIRM_ACCEPT_PROG
- If QCONFIRM_ACCEPT_PROG is set, its value is used
as prog argument to qconfirm-accept(8) in automatically created .qmail files.
- QCONFIRM_DIR
- The environment variable QCONFIRM_DIR overrides
the default location of the user’s qconfirm directory (‘‘.qconfirm/’’).
